Product Details

The COMP Cams 4842-1 flat guide plates are precision-engineered for Oldsmobile V8 engines from 350 to 455 cubic inches. These one-piece guide plates provide critical alignment for pushrods and rocker arms, ensuring proper valve train geometry and reducing side loading on valve guides.

Key Features:

  • Designed specifically for Oldsmobile 350-455 engines with 5/16" pushrods
  • Compatible with 5/16" rocker arm studs
  • Flat one-piece construction for durability and consistent alignment
  • Precision-machined openings maintain proper pushrod angle
  • Reduces valve guide wear by minimizing lateral pushrod movement
  • Essential component for performance valve train setups

Guide plates are recommended when using aftermarket rocker arms or performance camshafts to ensure optimal valve train stability. These plates help maintain correct pushrod-to-rocker arm geometry throughout the entire valve lift cycle, improving valve train efficiency and engine longevity.
